An old favourite online is back with a new design. TV Garden allows users to tune into free signals from around the world, mostly online news channels - so nothing illegal. It offers choices including Canada and the U.S. 

It also has a map of radio stations from various countries, which are on a right hand side map with call letters and locations where available. To find it, use the drop down TV icon at the top right of the page. 

And I have no idea if this was in the original, but there's also an around-the-world offering of porn channels, although I'm not sure I would trust many of the "stations" listed. To find the option, you'll have to click on the bell icon in the top right corner. 

You can check out the site here.
